I am new to the car scene and I was swapping out the green coolant for the red one when i remembered my friend suggested that I should put the water hose down from the top hose and water come out the bottom hose... But I realized that wouldn't that crack the block if the engine was hot... I did it like 3 times........

1) My car is not overheating but i see more white smoke coming out? (Smells like gasish and just exhaust) didnt really smell anything sweet. (Cars been warm already so many times and even when i took the video. Why is there still white smoke coming out? and when I rev it, more smokes comes out.Link: https://youtu.be/JKlZh_d-1zI

2) I checked oil cap and i saw a little milky things (cars been warmed up so many times prior for flushing) so I cleaned it off and I put it back. After driving for 20minutes I checked again and there was nothing(good sign?)

Yupper the old head gasket trick!!!I would not drive it until it fixed. There a good chance that you can screw up the head sealing surfaces. Buy an OEM or a good after market head gasket such as a Fel-Pro. Do not cheap out on a head gasket. The rest of the gaskets in a kit should not really matter. You might also want to look at a new timing belt [check condition before ordering parts] while you at it. If this is your first time removing the head, put paint marks on your cam pulleys, crank and belt after setting the engine to TDC on number 1 cylinder. Dave W7

If the car is not overheating, compression test is good, and it is still smoking. Then there is something else wrong. It could be many things (worn out piston rings, old valve seals, etc). I can speculate all day about it but I would perform a compression test first before moving further.

If it looks good, then provide us with some more information (sounds, smells, mileage, leaks, whatever).

what color is the smoke? if it is black or dark it is burning fuel (similar to a diesel) this pribably isnt your issue tho. if it is white it is coolant/water if it is white with a blueish color it is oil. iv never really been able to smell the sweet smell but color is a good indication. also check your plugs for fouling or if they look steam cleaned.

Hello, Yes, Car is not overheating but is still smoking. Whiteish smoke and earlier little gray and whiteish smoke. Smoking abnormally. Not crazy but more than usual that it is not normal. But could I mess it up like the rings by putting cold water into a hot engine when i did the flush?

Sounds: Sounds normal, but when i started earlier like 10 mins ago after compression test my friend said it sounded flooded but i started again and it sounded back to normal.Smell: Smells like gas from the exhaust.Mileage: 185kLeaks: NoneCompression: 1: 150 2: 1503: 1493: 149

Honestly It looked white with like gray and a super non existent hint of blue... Mostly white and little gray. I have linked a picture of my plugs below. Looks exact.

My exhaust smells like gas and it is smoking white but earlier today it seemed like it was kind of gray and whiteish. Running rich? But still don't know why it is smoking abnormally.)

"2) I checked oil cap and i saw a little milky things "SwookiThis is a tell tale indicator that you have water in the oil, i.e. head gasket, or worst a cracked head or block.If you want to comfirm the problem before breaking into the engine, take it to a shop and have them do a leak down test.Dave W

But then it disappeared after. It was like a white substance it was almost non existent. I checked the dipstick and the oil was normal.

Responding to everyone here helping.Just drove my car and tried to go to 6k RPM and it felt fine. Barely any loss of power noticed. No overheat. I got out the car when i got home and there was no smoke. After like 3mins I checked the oil cap and i noticed this.. Is this normal?What should i do?https://ibb.co/gm2ON6https://ibb.co/jmzg9m

It sounds like you got water in the engine some way but it appears that you have dodge the bullet. I would just keep an eye on the oil and also the coolant level. Put a mark on the coolant over flow bottel at it's current level. This will make it easy to tell the level is changing. DaveW7

The 'milky things' under oil cap was prob just condensation from moisture in the crankcase. Not uncommon to see in cool weather. (You also may see it in the valve cover breather.) When the engine reached temp it returned to the sump.

Yes... tend to agree that you are over-thinking this matter. If your oil is not showing any signs of emulisified water (milkshake) under the cap; the cooling system is not losing water, making steam or showing caramel foam under the oil filler, and running like normal; then most likely it is fine. Compression test comes back good also.

Water is a by-product of the combustion process, and some water vapor will find itself into the crankcase with normal blowby. That water will come out the breather once the engine gets nice and hot from a decent run. But make a lot of short trips when the engine never gets properly warmed up, and you will get sludge forming. Worse in winter as pointed out above. Best thing you can do is make sure it gets a good run every week

Hmmm... So I dodged a bullet?

Well the only thing it is showing is the two pictures i posted on this and that's all. The dipstick looks golden since i just changed the oil. So I should get the engine warmed up really good and get a nice run today. I don't need to change oil or nothing and for now just drive the car with the smoke? maybe it'll burn all off?

Yes... just drive it and give it some work to do Then when it has cooled down a bit, check the oil for water and the water for oil. Remember that there is always a little bit of water vapor coming out the exhaust. It warm weather you don't see it because it just dissipates into the air. But in winter the vapor condenses when it hits the cold air and turns into steam. Steam can look a bit like grey smoke coming out the tailpipe.
